Research summary
A cataract is a degradation of the optical quality of the crystalline lens that affects vision. Most cataract development is related to aging, and it occur in one or both eyes. Cataract is the leading cause of blindness worldwide. The management of visually significant cataract is primarily surgical. The predominant method of cataract surgery in much of the world is sutureless, small-incision phacoemulsification with foldable IOL (intraocular lens) implantation performed on an outpatient basis. Intraocular lens implantation is the method of choice, unless there are specific contraindications. Posterior chamber IOL implantation inside the capsular bag is the optimal method for most cases.
Cataract surgeons can choose from a wide variety of posterior chamber IOL styles and materials to find an appropriate lens to match their patients’ needs. Intraocular lens optic size, shape, haptic configuration, optic edge design, optic and haptic materials, and chromophore content are engineered with a variety of characteristics.
Foldable IOLs are commonly used because of their ability to fit through small incisions, and they have largely replaced rigid polymethyl methacrylate (PMMA) posterior chamber IOLs. Foldable IOLs can be made from silicone, hydrophilic acrylic, and hydrophobic acrylic. Surgeons should be familiar with the unique positive and negative features of each IOL type with regard to material, design, and insertion system.
Although numerous complications can occur intraoperatively or postoperatively, those resulting in permanent loss of vision are rare.
The purpose of our investigation is to retrospectively assess visual outcomes, refractive stability, safety features of the lens and the incidence of developing posterior capsule opacification in a 12-month period following mono- or bilateral implantation (as needed) of the hydrophobic acrylic monofocal IOL, Bi-Flex 877PAY (Medicontur).REC name
